SASH-WEIGHT.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed October 26, 1907. Serial N 0. 399,352.

To all whom it may concern:

Be it known that I, FERDINAND C. SCHWEDTMAN, a citizen of the UnitedStates, residing at St. Louis, Missouri, have invented a certain new anduseful Improvement in Sash- Weights, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich This invention relates to sash weights, and particularly to thattype which consists of a metal shell or housing incasing a core formedby the material of which the weight is essentially composed.

The main object of my present invention is to provide a sash weight ofthe type referred to having a cord-securing means ex tendinglongitudinally through the core and rovided with an incasing shell whichhas its ower end bent or folded inwardly to form a closure.

Another object of my invention is to provide a sash weight in which themetal shell that incases the core is bent or folded inwardly in a novelmanner to produce a closure for one end of the shell.

Figure 1 is a side elevation of a sash weight constructed in accordancewith my invention; Fig. 2 is a view at right angles to Fig. 1 and partlybroken away to more clearly show the construction of the sash weightshown in Fig. 1; Fig. 3 is a cross sectional view of the shell whichincases the core; Fig. 4 is a detail view illustrating the manner inwhich the upper end portion of the shell is bent or folded inwardly;Fig. 5 is a detail view showing how the upper end of the shell looksafter the o eration of folding in the side walls of same has beencompleted; Fig. 6 is an inside view of the upper end of the shell forthe purose of illustrating more clearly the manner 1n which the endportion of the shell is bent or folded inwardly; and Fig. 7 is a viewpartly in section of a modified form of my invention.

Referring to the drawings which illustrate the preferred form of myinvention, 1 designates a metal shell or housing that incases the core 2of which the sash weight is essentially composed, said core being formedof any suitable material. The shell 1 is preferably formed of sheetmetal and may either consist of a seamless tube or a plate bent to theproper shape and having its edges secured together, as for example, by aseam 1", as

shown is ofrectangular-shape in cross section and the end portions ofthe shell are bent or folded inwardly over cap pieces 3 arranged at theopposite ends of the core 2, said cap pieces being of approximatelypyramidal shape and formed either solid or hollow, as shown in Fig. 2. Amember 4 provided at its upper end with an opening or eye 5 forreceiving the cord which supports the weight, extends longitudinallythrough the core 2 and is connected at its lower end to the lower end ofthe sash weight, the cap pieces 3 having openings through which saidmember passes.

In the preferred form of my invention, as shown in Fig. 2, the lower endof the member 4 is connected by rivets or fastening devices 6 to thefolded-in portions of the shell 1 and to a clip 7 which embraces saidfolded portions, the folded or bent portions at the upper end of theshell having no positive connection with said member 4. The member 4 ispreferably formed by a flat metal bar and as said bar is secured to thelower end of the weight it carries or supports the core 2 so that thereis no liability of the closure at the lower end of the shell 1 beingweakened or disrupted when the sash weight is subjected to a suddenjerk, said bar 4 also stiffening and strengthening the weight. Theclosure at the upper end of the shell 1 is produced by bending the endportions of the sides a, a of the shell inwardly so that they will liesnugly against two oppositely disposed sides of the pyramidal-shaped cappiece 3 and then bending the projecting parts a of the portions a overthe two other oppositely disposed sides of the cap piece 3, as shown inFig. 4, the end portions of the shown in Figs. 3 to 6. The shell hereinsides I), b of the shell being bent inwardly to produce parts I) whichlie over the parts a of the shell and which cooperate therewith to forminwardly extending knife-plaits. The sides I), b are then subject tofurther inward pressure which causes the parts a, a to lie snuglyagainst the cap piece 3 and the parts I), b to contact with the parts a,a,

as shown in Fig. 5, thus forming a rectangular-shaped opening throughwhich the mem-- ber 4 passes, as shown in Fig. 2. In this way I form aclosure for one end of the shell without cutting the metal in the shell,by forming two single box-plaits of varying width, as shown clearly inFig. 4, the opposit'ely disposed sides I), b, constituting most of thematerial in the plaits and the parts a a of the sides a forming theunderneath folds of the plaits. Instead of securing the lower end of themember 4 to the folded portions of the shell and to the clip 7 whichembraces said folded portions, as shown in Figs. '1 and 2, said member 4can be secured to upwardly projecting wings 30 on the lower cap piece 30by fastening devices 31, as shown in Fig. 7. A sash weight of thisconstruction will be practically as strong as one of the constructionshown in Figs. 1 and 2 as the lower cap piece on which the core rests isconnected positively to the lower end of the member 4.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A sash weight comprising a body formed by a core and a metal shellincasing same and having its lower end portion folded or bent inwardlyto produce a closure, and a metal member extending longitudinallythrough the core and having its lower end connected to the parts whichform a closure for the lower end of said body; substantially asdescribed.

2. A sash weight comprising a core, a cap piece arranged at the lowerend of the core, a shell surrounding said core and bent into intimateengagement with said cap piece so as to completely incase same, ametallic cordsecuring member extending longitudinally through said core,and means for securing said member in position; substantially asdescribed.

3. A sash weight comprising an elongated body consisting of a core and ametal shell incasing same and having its lower end bent or foldedinwardly to form a closure, and a flat metal bar extendinglongitudinally through said body and having portions of the shell bentinto engagement with its side faces and secured thereto; substantiallyas described.

4. A sash weight comprising a core, cap pieces arranged at the upper andlower ends of said core, a metal shell incasing said core and having itsends bent or folded inwardly over said cap pieces, a cord-securingmember extending longitudinally through said core and also passingthrough said cap pieces, and means for securing said member in position; substantially as described.

5. A sash weight comprising a core, cap pieces at the u per and lowerends of said core, a metal s ell incasing said core and having its endportions bent or folded in wardly over said cap pieces, and a metal barextending longitudinally through said core and cap pieces and secured atits lower ends to the folded-in portions of the shell; substantially asdescribed.

6. A sash weight comprising a core, cap pieces at the upper and lowerends of said core, a metal shell incasing said core and having its endportions bent or folded in wardly over said cap pieces so as tocompletely incase same, a cord-securing member extending longitudinallythrough said core and projecting through the top cap piece, and meansfor securing said member inposition; substantially as described.

7. A sash weight comprising a core, and a rectangular-shaped metal shellincasing said core, the corner portions of the shell at one end thereofbeing folded or bent inwardly in such a manner that the end of the shellwill be completely closed and of pyramidal shape with four closed seamsor joints at the junction of the sides of the pyramid; substantially asdescribed. 7

8. A sash weight comprising a core, a pyramidal-shaped cap piece at oneend of said core and a rectangular-shaped shell incasing said core, twoof the oppositely disposed side walls at one end of said shell beingbent inwardly into engagement with two of the sides of the cap piece andalso extending partially over the other two sides of said cap piece andthe other two oppositely disposed side walls of the shell having theircorner portions folded inwardly so that they will lie upon the portionsof the shell that extend only partially over the sides of the cap piece;substantially as described.

9. A sash weight provided with a shell which is closed at one end bybending oppositely disposed portions of the shell inwardly and formingbox-plaits in the remain ing edge portions of the shell; substantiallyas described.

10. A sash weight provided with a shell having a rectangular-shaped endportion which is closed by forming single box-plaits in two of theoppositely disposed walls of the shell; substantially as described.

11. A sash weight provided with a rectangular-shaped shell having apyramidalshaped end produced by forming inwardly extending knife-plaitsin the corner portions of said shell and then bending two of theoppositely disposed side walls of the shell into engagement with saidplaited portions; substantially as described.

12. A sash weight provided with a shell which is closed at one end byforming oppositely disposed single box-plaits in the edge portion ofsaid shell and bending the intermediate edge portions of the shelltoward each other, said box-plaits diminishing gradually in width sothat a pyramidalshaped end closure will be produced; sub stantially asdescribed.
